Tooley Racing BTR LSA & LS9 Stage 2 Camshaft

This is possibly the best overall camshaft in the performance aftermarket for GM LSA and LS9 engines.  Will work great with any positive displacement supercharger on a 6.2 liter engine.  With -10 degrees of overlap it has a nice, mellow idle, but makes the power of much larger cams.  The secret is in minimizing the overlap, while maximizing the intake valve closing and exhaust valve opening events.  This cam has proven to make more power than other cams that have more lift, which makes this cam more durable.  Lift approaching .650" while using stock rocker arms with too much open spring pressure can damage valve tips long term.  Cam specs are 227/242 .614"/.592" 122+6 and comes a 3 bolt timing gear pattern.
